Missing channels after retune - where to get help?
David Plowman
I was at my mum's this weekend to retune her Freeview tellies. She has a
new set-top box which is receiving all channels correctly, and 2 tellies
with integrated digital TV tuners which (after retuning) pick up all
channels except (of course) the ones she cares about - BBC1, BBC2, BBC
News 24 (I assume, that whole multiplex). The 2 tellies are about 2
years old.
The postcode is NR15 and I'm pretty sure she receives from the
Tacolneston transmitter (the working set-top box lists BBC1 as coming
from UHF channel 63). On the other 2 tellies, I've tried deleting
everything and rescanning, I've tried manual rescanning (pointing it at
channel 63) but I get nothing. All the devices are fed from the same aerial.
Anyone have any suggestions? Where do I go to get help? Do I need to get
someone to come and look at her aerial?
Thanks in advance!

Either the tuners on the TVs are less sensitive than the one in the STB, or
they are getting a smaller share of the available signal.
How is the aerial signal split between the 2 TVs and the STB - is it just a
passive splitter, or is there a distribution amplifier?
What type of aerial is it - are you sure that it covers channel 63
adequately?
Have you tried connecting just once device at a time? If you plug each TV in
turn into the aerial socket normally used by the STB, you just *might* have
enough signal to get it to recognise the other mux. If you can find and
store those channels, they just *might* then work when the TVs are plugged
into their normal sockets.

bit strange. Have you tried taking the box around to the other sockets and
seeing if it will work after a rescan there? It could well be that the lower
gain at the high end is compounded by some extra losses, for whatever
reason, in the other feeds.

Sounds like a patch cable problem, are you by any chance using a moulded
patch cable that came with one of the STBs? Most of these are not
adequate for digital TV, so now people are starting to rely on them for
iDTVs its starting to show up.
If the cable ends of the patch leads are near any metal surfaces (other
than the receiver) such as a metal table or a DVD player casing, the
signal gets badly distorted.
The problem is the plugs are not shielded properly at the cable ends.
Solution is to make up a cable of your own with proper connectors, its
not easy to buy patch cables with proper shielding, most in the shops
are the same.

Cheap flyleads are often very badly screened, with poor connection methods
at the plugs. This shows up in all the ways you'd expect. Dunno about metal
objects though.

completely dissapeared from my freeview box. i retuned and still not
receiving them. I know ther were some updates to the service on 4th
Nov , would this be the cause and how do i recover the missing
channels

They've made a technical change to the multiplex that the main BBC
channels are broadcast on from Winter Hill (from 2k to 8k, not that I
actually understand what that means). What I do know is that some
freeview boxes are incapable of using this new multiplex as they can't
cope with 8k broadcasts.
Suggest you check your model against the list here, or post with your
freeview box make / model so someone here can give an informed
opinion.

BBC has changed from 2K to 8K but, even with a retune, your box
many still be looking for 2K.
A full software reset should clear the problem.

possible that you have other equipment befor the TV which has a
modulator feeding out on or near that channel (multiplex) which can
stop it working.
Some Panasonic and Sony VCRs leave the modulator on even when the VCR
is in standby, generating a strong, blank carrier.
